MIXING-MACHINE FOR PAINTS.

SPECIFICATION forming part of Letters Patent No. 336.079. dated February16, 1886.

Application filed December 16, 18S/1. Serial No.150,541. (No model.)

To @Z whom t may concern:

Be it known that I, NATHAN BAssETT, a citizen of the United States,residing at Haddonfield, in the county of Camden and State 5 of NewJersey, have invented certain new and useful Improvements in Mixing andSifting Machines, and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in io the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the letters andtigures of reference marked thereon, which form a part of thisspecification. Y

My invention relates to an improved machine for making and sifting drymaterialsuch as self-raising our, baking-powder, colors, spices,fertilizers, and, in fact, any material that is not gummy or sticky, andhas for 2o its object to thoroughly sift and clean, and to break uplumps, before passing the material to the mixing cylinder or drum, andto thoroughly and expeditiously mix the particles of two or moreingredients together.

To these ends my invention consists of the construction, combination,and arrangement of parts, substantially as hereinafter more fully setforth, and pointed out in the claims.

In the drawings hereto attached, Figure l 3o is a longitudinal verticalsection on the line a w of Fig. 2; and Fig. 3 is an end elevation of themachine, showing the hopper and driving-gear. Figs. 4 and 5 aretransverse vertical sections on the lines l l and 2 2, respect ively, ofFig. l. Fig. 6 is a sectional view showing the means for supporting oneend of the mixing cylinder or drum. Fig. 7 is a horizontal section onthe line y i/ of Fig. 2; and Figs. 8,9, and l0 are detail views of parts4o of my improvements.

Similar letters of reference in the several Y drawings denote like orcorresponding parts.

ported at one end in a bearing, c', formed in, the lower end of asupporting-bracket, hereinafter described, and secured to one of thewalls of the inclosing-case A, while the other end of said shaft ismounted in a box or bear-` ing. c2, supported in a standard, C', firmlyand rigidly bolted to the floor, said shaft being provided with fast andloose pulleys C2, by means of which motion from any suitable motor iscommunicated to said shaft. The drum or, cylinder, having ends or headsB/ B2, is provided withshafts D D D, arranged at equidistance apartaround the circumference and within the inclosingwall thereof, and areprovided with spirally-arranged blades d, and pass through and bear inone of the heads, (at the left-hand end B,) where they are provided withrollers or pulleys d', which bear against the inner edge of acircumferential rim, 612,01 7o a bearing or journal plate or bracket, E,secured to the inner surface of one of the walls of the inclosing-casingA, near the top thereof, (see Figs. l and 6,) thereby wholly supportingthe drum. The opposite ends of the shafts have their bearings in thehead B2 of the drum or cylinder, as at d3, (see Fig. 1,) the said headB'Z being provided with a central opening or aperture adapted to receivethe inwardly-projecting end of the bottom of the 8o hopper, therebyproviding a support for that end of the drum, as more fully hereinafterdescribed.

F designates a hopper suitably secured to the front Wall of the frame A,having sloping side walls,f, and divided into two compartments by acentral partition, f2. In the lower end of said hopper is a chamber, F',formed by converging side walls, g, and a bottom, y', made semicircularfor a portion of its length 9o equal to the width of the hopper, andthen made cylindrical, as at g2, for the remainder of its length, saidcylindrical portion proj eeting through and bearing in the front wall ofthe inclosing-case A, and having its extreme inner end slightly reducedand fitting into the aperture o1' opening in the head BIl of thecylinder or drum, as atga, thus providing a bearing for the drum at thefront end of the frame or case A. The hopper is supported by a roobracket, H, having the bearing c for the driving-shaft C formed at itslower end, said bracket being secured to the front wall of the Case A.and supporting ab its upper end the Walls and bottom of the chamber F,and also 'the side walls of the hopper,which are secured thereto. Thelowerv end of the hopper has openings communicating with the chamber F',andacross-these openingsIplace semicircular screens or sieves GG',having their ends se,- cured to the walls and partition of the hopper,as shown in Figs. 1 and 2, and meshes of different sizes. Immediatelyabove the screens G G', I place shafts H H', having a series of bristlesor brushes, 7L, arranged spirally thereon, said shafts having theirbearings in the walls of the hopper, one end of eachV of said shaftsprojecting through the front wall of the hopper, and there provided withpulleys I, driven by a belt, J, from a pulley, J', on the driving-shaftC.

" Kdesignatesaconveyer-shaft,provided with a spirally-arranged plate,ic, located in the chamber F' of the hopper, the outer end of said shaftbearing in and projecting through the front wall ofthe hopper, where itis pro vided with a pulley, k', driven by the belt J.' from thedriving-shaft C, the inner end of said shaft having its bearing'- in askeleton frame, j, secured tothe inner surface ofthe head B2 of the drumor cylinder B.

By reference to Fig. I of the draw-ings it will be'seen that the bladesofl one ofthe mix-- ing-shafts D D Dfpreferably the shaft Dseis arrangedin a direction reverse to thatof the blades of its fellow shafts,whereby the materials to be mixed in the drum are conveyed back andforth therein, and forced outwardlyA from said shafts foward thecircumference and h-eads thereof, thereby thoroughly mixing andcommingling the particles together in a thorough manner, and requiring aminimum of time for the operation. rIhe case A is provided With a doorin one ofv its side walls, through which a suitable receptacle or box ispassed to receive the materials from the drumor cylinder B,after thesame has been cleaned and mixed. The drum is provided with an opening,b', in one end of its circumference, for discharging the materials, saidopening being closed by a gate or door, b", sliding in ways or cleatsb3, secured to the said drum. @See Figs. l and 5.)

The operation of my invention is as follows: The materials to be mixedare placed in the chambers of the hopper, and power from any suitablemotor is applied to the driving-shaft through the fast pulley C. Themotion of this shaft is communicated to the brush shafts H H vthroughthe belt J, which force the materials through the sieves G G', thuscleaning the same of any refuse matter, and breaking up any lumpstherein. The materials fall through the sieves in a cleaned state intothe chamber F', and are carried into the mixing cylinder or drum B bythe conveyer K, driven by the belt J. The cylinderor drum is ref. volvedby pQwer transmitted from the driving.

broken, before being shaft C through the pinion c, securedthereon, and.the geared .rimj b of the'head B2 of the drum, said drum carrying'themixingshafts D D D with it in its revolution, and causing the rollers orpulleys d' thereof to bear or irnpinge against the circumferential rimof the bracket E, thus revolvingf'tllel,said shafts, and causing them toconvey the materials back and forth in the drum, whileat the same timethey force the same outwardly therefrom toward the circumference andheads of the drum, as before described.

It will be observed from the foregoing de- SGIfiptiQn that I provide asimple la'nddurable machine, one which requires a minimum of power todrive the same, and which will quickly and expeditiously accomplish themixing of any ma'terialsin athorough manner'.

Mymachine is adapted for themixing of paints, bran, or any othermaterial, while at the same time the materials are thoroughly cleaned,and the lumps, if any therein, are

u fed tothe mixing-cylinder.

be made without departing from theprinciple or sacrificing theadvantages of my invention.'

and I would therefore have it understood that I hold myself at libertyto make such changes and alterations as fairly fall withinthe scope ofmy invention.
